Title: Method for removing solder
Inventor: HAYASHI MASARU
IPC: C23F1/44
Filed: 1995-05-22
Abstract: PURPOSE: To remove and recovery solder from a soldered article very easily, inexpensively, safely and perfectly by bringing the article into contact with an aqueous hydrogen chloride solution of a specified normality or below. CONSTITUTION: The article to be treated is cut so that the pieces may be so uniform in size that they are 5-20 by 5-20cm squares. It is necessary that the normality of the aqueous hydrochloric acid used is 11 or below, desirably 6-10. In order to shorten the dissolution time of solder, it is desirable that the contact with the solution is performed under heating. However, when the temperature is excessively high, substances other than the solder to be dissolved are dissolved and contaminate the treatment solution. It is desirable that the contact temperature is 40-80 deg.C. It is desirable that the contact is performed under pressure. Desirably, the pressure is 4-10kg/cm<2> .G.  The solid solder component is recovered, for example, by bringing the solder solution into contact with a metal having an ionization tendency higher than those of lead and tin or concentrating the treatment solution.

Title: Control circuit for agc amplifier
Inventor: GOTO HARUHIKO
IPC: H04L27/38
Filed: 1987-05-20
Abstract: PURPOSE:To design the titled control circuit to allow the AGC amplifier to follow the fast level fluctuation of an input signal by using a signal excluding the amplitude modulation component included in the output signal of the amplifier of a multivalue QAM signal as control information. CONSTITUTION:A logic circuit 2 multiplies an output data of an A/D converter 1 with a reciprocal of a ratio with a substantial amplitude obtained from output data I, Q of a demodulator to arrange the level into a substantial amplitude. The output of the logic circuit 2 represents only the phase modulation component being eliminated the amplitude modulation component of a carrier signal (multi-value QAM signal) subject to multi-value orthogonal amplitude modulation from the output of an IF amplifier 5B. A binary error signal with a setting value outputted from a comparator 3 is converted into an analog signal A by a D/A converter 4 and a voltage obtained by integrating the signal A by an integration device 5 is used as a control voltage Vc of a variable attenuator 6 to vary the attenuation. Thus, the time constant of the integration device 5 is selected to a small value and even when the input signal level of the AGC (automatic gain control) amplifier is fluctuated at fast speed, the circuit can follow sufficiently the input signal level.
